Break the language barrier — in real time, on the front line.
Real-time AI translation for policing, courts & prisons
Turn live speech into accurate, AI-validated translation across 18+ languages. Designed for police custody, policing, courts and prisons teams where a clear conversation cannot wait.
Secure, UK-hosted and ready to plug into the systems you already use.
When every word counts, waiting for an interpreter isn’t an option
Across policing, the courts and wider criminal justice sector, frontline teams meet people every day who do not speak English, and the stakes are highest exactly when communication is hardest. Booking a human interpreter can mean long delays, agency costs and a person left waiting when their welfare, rights and needs must be understood quickly.
Generic translation apps were not built for regulated, high-risk settings. They can mishear specialist terms, offer no defensible record and give no assurance that wording is accurate, appropriate or safe to rely on.
What frontline teams are up against
- Interpreter delays and cost, especially out of hours and for less-common languages.
- Safety-critical assessments, custody risk, welfare checks and interviews – that cannot proceed until the person can be understood.
- Consumer apps that misread specialist terminology and offer no audit trail.
- No assurance that machine translations are accurate, appropriately toned or defensible.
- Data-protection concerns around sensitive conversations and unknown public-cloud tools.

Real-time translation built for the front line - not borrowed from the consumer market
Mobilise listens, translates and validates live speech as the conversation happens. Every sentence is checked by AI for tone and appropriateness before it is shown, while the exchange is captured as a secure, exportable record.
Delivered as a fully managed, AWS-native service in a PDS-accredited landing zone, it runs through a clean web interface or integrates with the systems your teams already use.
Three things make it different
Domain-tuned speech recognition and an AI correction pass recognise specialist terms instead of guessing.
Every translation is AI-checked and retained as a secure, exportable transcript and audio file.
Proven in custody and configurable for structured conversations across policing, courts and prisons.
Everything you need to hold a clear conversation across a language gap

Languages can change mid-conversation without restarting.
Amazon Bedrock checks tone and appropriateness before wording is shown.
Custom vocabulary biases recognition toward the terms your teams actually use.
Structured multilingual questions with intelligent, context-aware follow-ups.
A map-based picker helps staff set the right language with one tap.
Downloadable records support review, disclosure and audit.
Run distinct conversations and retrieve history with role-based access.
In focus: a guided risk assessment, in the person’s own language
Current flagship deployment
Our most developed application is a custody check-in workflow. It walks a person through a standard custody check-in and risk assessment in their native language: asking the right questions in the right order, translating both questions and answers, and using AI to generate sensible follow-ups.
The result is a consistent, documented welfare and risk conversation that does not depend on an interpreter being available the moment a person arrives — with a clear record of what was asked and answered.
Why it is the proof point
- Standardised questions from the risk-assessment set, asked consistently every time.
- Intelligent, context-aware follow-ups rather than a rigid script.
- Extended language coverage for high-pressure settings.
- A complete, exportable record for welfare, compliance and handover.
Custody is the hardest, highest-stakes test: regulated, time-critical and safety-driven. Proving the approach there means the same guided, recorded workflow can be adapted with confidence across policing, courts and prisons.
Decision-support, not a replacement: the service supports trained staff and bridges gaps when an interpreter is not immediately available. It does not replace professional judgement or a human interpreter where one is required.

From spoken word to validated record in four steps
Speak or type
Staff talk naturally; live speech-to-text captures each turn, cleaned up for clarity before it is processed.
Translate
The text is translated in real time, with terminology tuned to your domain.
Validate
AI checks tone and appropriateness before the translation is shown.
Record
The exchange becomes a secure transcript and audio file with chain of custody.
“Built and secured by an AWS Advanced Consulting Partner trusted by UK government and enterprise.”
Engineered for sensitive conversations and regulated environments
Mobilise’s service is built on AWS to the same standards applied across UK government and enterprise customers. Sensitive conversations stay protected in transit and at rest, access is controlled and logged, and records support audit and lawful disclosure.
These points describe the platform’s technical design. Mobilise’s organisational ISO and Cyber Essentials Plus credentials are shown separately above.
Use the app, or connect it straight into your existing systems
Already have a case-management, custody or court system your teams live in? You do not need another window to switch to. The same translation and guided-workflow capabilities are available through a secure REST API, so results can flow directly into the tools your people already use.
Built for partner agencies and software vendors
- A clean REST API with per-organisation keys and usage controls.
- Asynchronous results delivered through signed webhook callbacks — no polling required.
- Direct, serverless processing designed for reliability and predictable performance.
- Straightforward onboarding for new organisations, with secure credential exchange.

Frequently asked questions
Is this just for police custody?
No. Custody is our most developed, proven use case — but the underlying service is a real-time translation platform for policing, courts and prisons. The same guided, recorded, multilingual workflow can be configured for other structured conversations such as court and immigration interviews, victim and witness statements, and prison casework.
Does this replace human interpreters?
No. The service is designed to support trained staff and bridge the gap when an interpreter is not immediately available. It complements professional interpreting and human judgement rather than replacing them.
Where is our data stored?
In the AWS London (eu-west-2) region, encrypted in transit and at rest, within a PDS-accredited landing zone with access controlled by authenticated, role-based login.
Can we keep a record of conversations?
Yes. Every session can be exported as a text transcript and an audio recording, and records are retained for review, audit or lawful disclosure with a full chain of custody as standard.
Can it work with our existing systems?
Yes. Alongside the web app, a secure REST API lets you route translation and guided workflows directly into your existing systems, with results delivered via signed webhook callbacks.
Which languages are supported?
18+ languages today, with extended coverage in the custody workflow. Further languages can be added on request.
